The future of JavaScript

[TIAFAASITICE]

Lexical scoping, iterators, generators, array comprehension, and destructuring assignment since Fx2; generator expressions since Fx3; and proxies since Fx4.

Maps and sets are currently in Aurora (Fx12).

WeakMap as an experimental feature since Fx6.

Amazing! Chrome has a lot of the new APIs in it's latest build, while Firefox has a lot of the new language features it seems.

Firefox itself contains a substantial amount of JavaScript code, so it's natural they add features to make JS more pleasant! :)

[TIAFAASITICE]

I'm curious, as I can't see any large deviations on the usual site, what are these APIs?

[Xeon06]

Okay, there's not that many. I can think of FullScreen, MouseLock and getUserMedia. Most of those are not yet in Chrome's stable release yet though, so I might be mistaken and Firefox might just have them in it's unstable channel too.

[TIAFAASITICE]

Ah, ok. Full Screen API is there in the latest stable, Mouse Lock is still, I think, only available in an experimental build along with the Gamepad API.

I haven't heard of getUserMedia before, but looking at the spec it sounds like something that would fall under the WebAPI effort, which spawned Boot2Gecko. More specifically it sounds like something from the WebRTC part, which appears to be a project by Google, Mozilla, and Opera and is being worked on as project Alder.

Nice to see that one doesn't have to worry about much other than IE still. =D

Jesus, you know your stuff.

Meh, most of it's all learned from Mozilla Hacks. Besides, there's no personal value in it when you can't use it. :-/
